Security Solutions (SES) is a globally acting business unit within the Siemens' division Building Technologies. A part of the headquarters' activities is the development and provision of solution packages for the regional sales organizations. In the past, this was a very centralist process with limited or none participation and feedback of staff coming from regional organizations. To improve this situation, we introduced an interactive and fully transparent process motivating regional colleagues to directly participate during all process stages (requirement collection, technical development, global roll-out, solution lifecycle). We identified relevant experts and grouped them in a 'SES Solutions Community', which is networked not only by personal meetings, but also by several Web 2.0 instruments.
